Ice age study delivers blow to global-warming skeptics
Changed patterns of deep sea circulation resulted in less sea ice around Antarctica at the end of the last ice age, part of a broader process that led to an influx of carbon dioxide in the atmosphere. This photo shows Antarctic sea ice today.
A new study finds that rising levels of carbon dioxide drove rising temperatures at the end of the last ice age. The findings contrast with previous studies, which skeptics of human-triggered global warming said showed that CO2 levels weren't an important factor.

CO2 'drove end to last ice age'
Ice core records from Antarctica had suggested the CO2 increase lagged behind temperature rise
A new, detailed record of past climate change provides compelling evidence that the last ice age was ended by a rise in temperature driven by an increase in atmospheric carbon dioxide.
